An autotransformer is a simple and inexpensive way to correct problems that arise when a secondary voltage is difficult to obtain or a transformer you have is either too high or too low. A transformer that has a part of its winding included in both the input and output circuit is known as an autotransformer. In a simple autotransformer connection there is a common portion of the winding that has no isolation between the input and output circuits, and there is only one winding. The secondary current rating of an autotransformer must be at least equal to the primary current rating of the subject transformer.  In simple terms, a subject transformer with a primary current draw of 5 amps should be used with an autotransformer with a secondary current rating of 5 amps or more.  Dyco Electronics manufactures custom surface & PCB mount,MIL-PRF-27, XFMR, toroid, control, 60 HZ, flyback, audio, switching, swinging, chokes, auto, and 3 phase transformer products. A 3 phase transformer is found in most large power - and small - transformer installations which provide all 3 phases. Sometimes they do so with three single-phase unit, sometimes with one 3 phase transformer unit. In either case, there are six windings, three on the primary and three on the secondary side.

A transformer is a device used in an electrical circuit that changes a voltage on the primary winding to another voltage level on the secondary winding(s). This transformation is accomplished via a mutual coupling effect between the primary winding and secondary winding(s), with the magnitude of change determined by the turns ratio between the windings. If the primary winding contains more turns than the secondary winding, then the voltage induced in that secondary winding will be decreased by an amount equal to the turns ratio between the primary & secondary winding, a transformer that does this is referred to as a step down Transformer. Whereas in a transformer that has a primary winding with less turns than the secondary, then the voltage induced in the secondary winding is increased by an equal amount to the turns ratio, this device is called a Step Up Transformer. Dyco Electronics manufactures a wide range of military and commercial magnetics. We make transformers, reactors, inductors, chokes, coils...just about anything that involves copper foil or copper magnet wire. We also do simple electrical and mechanical assemblies and have extensive molding and potting capabilities.

Either way we are committed to bringing increased value to you the customer because we do believe that in your success lies our success! Impedance, (Z) is a measure for the manner and degree a component resists the flow of electrical current if a given voltage is applied. It is denoted by the symbol Z and is measured in ohms. Impedance differs from simple resistance in that it takes into possible phase offset. For a magnetics component impedance is comprised of the copper loses due to the resistance of the magnet wire and the inductive reactance losses associated with the changing magnetics and electric field losses. The summation of these resistive and reactive loss components are performed with vector addition. The permeability of a magnetic material about a specified operating point and applied magnetics field strength, especially under DC bias conditions. The incremental permeability is expressed as the slope of the B-H characteristic about the given operating point (dB/dH). Isolation transformers are transformers with a one to one turns ratio, where one side is connected to the source and the other to the load. Used to prevent any DC bias levels present on the source from passing through to the load. Isolation transformers can carry high frequency noise on the input primary to the output secondary windings so they are typically designed to minimize this capacitive coupling.

Coupling is a measure of the amount of interconnecting flux lines between two windings of a magnetic component or two magnetic components. For a current transformer the designer maximizes coupling between the windings by placing the windings on the same core and through various winding techniques. For individual inductors a magnetic shield is often placed over the windings to prevent flux lines from radiating from the winding and interfering with other components. Dyco Electronics is a manufacturer of high voltage power supplies & custome transformers for the static elimination ind. , 115 & 230 volt inputs with 4,000 to 8,000 volt outputs. Prototype & design svc. J-STD-001 certified soldering instructor on-site. Custom transformers are devices made to your specifications and employed in an electrical circuit that changes a voltage on the primary winding to a different voltage level on the secondary winding(s). This change is made through a reciprocal coupling effect between the primary winding and secondary winding(s), with the magnitude of alteration determined by the ratio of turns between the windings. If the primary winding has greater turns than the secondary winding, then the voltage induced in that secondary winding will be decreased by an amount equal to the turns ratio between the primary & secondary winding. A custom transformer that does this is referred to as a Step Down Transformer. Whereas in custom transformers that has a primary winding with less turns than the secondary, then the voltage induced in the secondary winding is increased by an equal amount to the turns ratio, this device is called a Step Up Transformer. The flyback circuit utilizes the "flyback" action of an inductor or flyback transformer to convert the input voltage and current to the desired output voltage and current. A modern flyback transformer and circuit design can now permit use in excess of 300 watts of power, but most applications are less than 50 watts. A flyback transformer first saves energy received from the input power supply (charging portion of a cycle) and then transfers energy (discharge portion of a cycle) to the output, usually a storage capacitor with a load connected across its terminals. A modern flyback transformer is operated at high frequency hence gapped ferrite core materials are typically used. You can find a flyback transformer in all sorts of screens and monitors which require a cathode ray tube (CRT) including television screens and computer monitors. The flyback transformer has many purposes - the creation of the acceleration voltage for the CRT (typically 20-30kV), and of many auxiliary voltages.

Design & prototype svc. J-STD-001 certified soldering instructor on-site. Various Dyco Electronics' magnetics and power transformer products are used for military and commercial capabilities such as critical military applications, and with several companies coming from many areas of the railroad industry. A power transformer normally operates from either 60 Hz, or 400 Hz alternating current. Each tiny domain must realign itself twice during each cycle, or a total of 120 times a second when 60 Hz alternating current is used. The energy used to turn each domain is dissipated as heat within the iron core. This loss, called HYSTERESIS LOSS, can be thought of as resulting from molecular friction. Hysteresis loss can be held to a small value by proper choice of core materials. Dyco Electronics is a manufacturer of the toroidal transformer, reactor, inductor, MPP, ferrite, tape wound, iron powder, common mone, bank wound, pulse transformer, hand wound, hook wound. Design svc A toroidal transformer is known to be one the highest performing transformer. A toroidal transformer has the smallest size (by volume and weight), inferior leakage inductance, and an electromagnetic interference (EMI) that is much lower. The use of a toroidal transformer is good for any transformer application that can accommodate its shape. Although usable, a toroidal transformer are not always practical for some applications. Dyco Electronics, Inc. is proud to offer a line of high voltage transformer supplies for use with static neutralizing equipment. Within a magnetic component for electrical components such as a voltage transformer there is a capacitive effect that occurs between turns, between layers, between windings (if there is more than one), between winding and core and between winding and encapsulant. This os what is known as distributed Capacitance (Cd).
